ATTENTION !
Descending pipe in operation, may reach high temperatures and consequently must not
co me in contact with flammable materials which may lead to their auto-ignition.
Catalytic converter is to be mechanical shock protected.
DISMOUNTIN G
In order to di smount the noise a bsorber assembly ( 1), lift t he ve hicle on an elevator and
perform the following operation s:
Loosen the nuts ( 2) of the attachment collar between the expansion chamber ( 3) and the
noise silencer ( 1).
Di smount the thre e a ttachment e lastic supports of the noise a bsorber, on the carri age
body, rear pa rt. Release the noise silencer.
In order to dismount the assembled expansion chamber (3), perform the following operations:
Di smount the c ollar ( 4) and disengage the e xpansion chamber assembled with the de -
scending pipe.
Dismount the three elastic supports of the assembled expansion chamber.
Loosen the attachment collar nuts ( 2) and remove the assembled expansion chamber by
easy rotation and onward pulling.
In order to dismount the descending pipe assembly (6), perform the following operations:
Dismount the engine shield.
Dismoun t the catalytic converter attachment nuts ( 7) on the two studs of the exhaust manifold
flange. Dismount the attachment screws of the converter support ( 5).
For EURO 96, dismount the oxygen sensor located in upstream of the catalytic converter.
For EURO 00, dismount the oxygen sensors located in upstream, consequently, in
downstream of the catalytic converter.
Dismount the collar (4) and disengage the assembled catalytic converter from the assembled
expansion chamber.
Remove the descending pipe.
REMOU NT I NG
Perform the dismounting operations in the reverse order.
Ensure a perfect sealing between the exhaust assembly elements, using sealing paste Wurth,
on the joining area length (inside) between the noise absorber – expansion chamber (0.013 Kg);
The oxygen sensor gasket is to be replaced at each dismounting.
The tightening moment between noise absorber and expansion chamber is: 3.6 daNm.
The tightening moment of descending pipe attachment nuts on the exhaust manifold flange is:
2 daNm. Tightening moment between the catalytic converter and expansion chamber: 2.5 daNm.
All elements are to be assembled having the ambient temperature.

IMPORTANT
During the intervention on the fuel tank or on the
fuel supply circuit, it is absolutely necessary:
-n ot smoking and not bringing near any incan-
d escent parts in the working area;
-gu ard against possible petrol leakage, due to
residual pressure remained on piping, when
dis mounting.
DI SMO UNT I N G
In order to dismount the fuel pump assem bl y it is
not necess ary the tank dismounting, the access being
done t h rough the vehicle trunk.
In order to do that:
-d isconnect the battery;
-d ismount the attachment screws of the fuel
tan k v isiting cover;
-d isconnect the electric connector (B) of the
fuel pump assembly supply;
-d isconnect the rapid coupling (A) of t he fuel
supply pipe. Dismount the fuel pump assembly (2) attachment

the arrow existing on the pump cap.
Release the fuel pump assem bl y.
REMOUNTI NG
Mount the fuel pump assem bl y on t he fuel tank
obs ervi ng the marking done when dismounting.
Mount the attachment nut of the fuel pump
assembly. Tighten the nut by means of the MOT 1397
device, so that the arrow from the nut meets the
arro w from the fuel pump assembly (this is ensuring
the minimal necessary tightening for sealing
achi ev ement.
REMARK :
After each dismounting, obligatory
replace the nut and its gasket.
The gasket will have the same color with the
dismounted one.

30Brake fluid
PERIODIC CHANGE OF THE BREAK FLUID
The m anufacturing conception of t he brakes equipping t he Dacia vehicles especially the
ventilated disk brake, enable the maximum diminishing of the fluid vaporization, even in case of
intensive using of brakes (mountain area), due to good disk cooling.
The brake fluids, suffer in all cases a slight degradations during the use, by a slight humidity
absorption, that makes necessary the complete replacement after a period of time or after some
driving (4 years or 60,000 driven km)
COMPLETION OF THE BRAKE FLUID LEVEL
The wear of brakes pads and shoes, leads to a gradually diminution of brake fluid level in its
reservoir. It is useless to compensate this diminution, because the level will be restored when changing
the brake pads and shoes.
Obviously , in the meantime, the level of brake fluid in reservoir must not go down bellow the
MINI mark.
HOMOLOGATED BRAKE FLUIDS
The mixture in t he braking circuit of two non different brake fluids may leads to important
risks mainly due to gasket damage, incompatible with new fluid.
In order t o a void such risks, it is obligatory to use only bra ke fl uid re commended by the
producer, i.e. : SAEJ 1703, DOT 4.

Chara cteristics
The front axle is composed of two joint half axles with independents wheels, designed for the
suspension type Mc.Pherson.
The joints of front half axle arm are done by means of an elastic bearing (chassis side) and by
means of a suspension ball joint (wheel side)
The transmission of the motion to the wheels is done by means of two planetary a xles, not
equal, with homocinetic tripod joints.
The wheel hub is assembled in the steering knuckle by means of a sealed bearing.
The brake disks a re ventilated.
